AWS CloudFormation Deletion Policy


AWS CloudFormation Deletion Policy Deleting a stack on CloudFormation also removes all the provisioned resources in it. In some cases, you want some resources to be retained even after deleting its stack. The good thing is that you can do this by defining its DeletionPolicy.  This is pretty straightforward - you just need to define DeletionPolicy with Retain value and for the resources that support snapshot, (like RDS databases) you can set Snapshot as its value. With DeletionPolicy: Snapshot, a snapshot is created before a resource is deleted. This allows you to have a backup of the resource that's been [...]

AWS CloudFormation StackSets and Nested Stacks


AWS CloudFormation StackSets and Nested Stacks AWS CloudFormation lets you model and provision resources for your environment using programming language, leveraging the concept of Infrastructure as Code (IaC). You don’t need to manually create all of your resources one by one, CloudFormation will do this for you. All resources are defined on the AWS CloudFormation template. This means that this AWS environment can be reliably and easily reproduced since everything is declared on a template. For example, creating a new Test environment similar to your current setup, or when creating a Disaster Recovery environment in another region.  With AWS CloudFormation, [...]

Amazon S3 Access Points


Amazon S3 Access Points Managing access to your S3 buckets should be pretty easy using Amazon S3’s bucket policy. But as the number of your users and data grows, this easily becomes a complicated task. Provisioning access policies (who and where to access these objects) to these users could be a messy thing to do. AWS added this feature called Access Points on S3 to resolve this current problem. Access Points can simplify things in terms of provisioning access to different users. With this feature, each user can have a dedicated access point on a bucket and each of these [...]

Amazon S3 Event Notifications


Amazon S3 Event Notifications With Amazon S3 being virtually unlimited in size, it's quite a challenge to keep everything monitored especially when you are dealing with a large number of objects that scales up from time to time. With Amazon S3 Event Notifications, you’ll be able to immediately know when an object in your bucket was created, removed or restored. This feature allows you to get notifications every time an event happens on your S3 bucket. These notifications can then be forwarded to Amazon Simple Notification Service (Amazon SNS) topic, Amazon Simple Queue Service (Amazon SQS) queue, and AWS Lambda. [...]

Configuring Notifications for Amazon EC2 Auto Scaling Lifecycle Hooks


Configuring Notifications for Amazon EC2 Auto Scaling Lifecycle Hooks Auto Scaling Lifecycle Hooks In the previous post, we talked about Auto Scaling Lifecycle Hooks and how to configure it on your Auto Scaling group. You can view the article here. It’s better to read it first before proceeding with this section. In a nutshell, Auto Scaling Lifecycle Hooks allow you to put an instance in the “wait” state while the Auto Scaling group responds to a scale-out or scale-in event. While the instance is in the “wait” state, you perform actions such as installing the application before allowing traffic to [...]

AWS Secrets Manager vs Systems Manager Parameter Store


AWS Secrets Manager vs Systems Manager Parameter Store Managing the security of your applications is an integral part of any organization especially for infrastructures deployed in the cloud. One aspect of application security is how the parameters such as environment variables, database passwords, API keys, product keys, etc. are stored and retrieved. As a best practice, secret information should not be stored in plain text and not be embedded inside your source code. It is also recommended to set up an automated system to rotate passwords or keys regularly (which is easy to forget when you manage keys manually). Managing [...]

Global Secondary Index vs Local Secondary Index


Global Secondary Index vs Local Secondary Index A secondary index is a data structure that contains a subset of attributes from a table, along with an alternate key to support Query operations. An Amazon DynamoDB table can have multiple secondary indexes. Global Secondary Index Read/Write Capacity Calculation (Provisioned Throughput Mode) Eventually consistent reads consume ½ read capacity unit. Therefore, each query can retrieve up to 8KB of data per capacity unit (4KB x 2). The maximum size of the results returned by a Query operation is 1 MB. The total provisioned throughput cost for a write consists of the sum [...]
